“…On the 3rd or 4th day after weaning, increase in epithelial height and glandular development are noticed. Snyder and Corner (1922) further substantiated the earlier observa tions of Corner (1921) that cilia are not present on the surface epithelium at any stage of the estrus cycle but are present in the uterine glands. Contrary to this observation, Lovell and Getty (1968) observed that many ciliated cells are present on the surface epi thelium of the cephalic end of the uterine horns near the utero-tubal junction of the sow at 8% and 27 hours after natural service.…”

“…Ciliary action can hardly be invoked as a factor of importance in connection with either egg or sperm transport in the uterus, for where present cilia occur sporadically and their number is hardly sufficient to function in any very important manner. It must be admitted, however, that ciliated cells are normally present on the uterine epithelium (Hoehne, , 1911Widakowich, 1910;Snyder and Corner, 1922). The stroke of the cilia is outward, i.e., toward the vagina.…”

Ovulation is the sine qua non of reproduction. It is a sharply demarked event, like birth or death; hence cyclic sexual phenomena in the maternal organism are most conveniently separated into those occurring before and those occurring after ovulation.By ovulation is meant the freeing of the ovum from the ovary and its expulsion into the body cavity, or into the ovarian bursa. Fertilization takes place in the body cavity, or, more usually, after the egg has been engulfed by the infundibulum of the oviduct and started on its journey to the uterus or the exterior. This is the typical procedure. However, in some fishes, the ova are fertilized within the follicle, the wall of which becomes modified into a nutritive organ, a kind of womb, in which the embryos develop for a time. In such cases ovulation and birth may be said to be synchronous. In other forms (Zoarces, e.g.) the eggs are shed but are retained within the ovarian capsule. The spent follicles, homologues of the corpora lutea of higher forms, undergo hypertrophy and become highly secretory, producing pabulum for the embryonic fish. The nutritive function of these "corpora lutea" is thus exemplified in a literal and diagrammatic way. These cases and many others that could be cited are exceptional but from a theoretical standpoint highly instructive, representing as they do primitive conditions which are postulated as theories when applied to man and other mammals (cf. Kohn in "Synkainogenese," 1916).
